Die 3- und 7-Hydroxygruppen können dazu vorübergehend als Formiat (Abspaltung mit NH3/MeOH) oder p-Methoxybenzylether (Abspaltung mit DDQ) geschützt werden.For epothilones A and B, reference is made to DE-A-41 38 042. Compounds according to general formula 1 are based on epothilones A and B and on their 3-O- and / or 7-O-protected derivatives by opening the 12th 13-epoxy accessible. Hydrogen acids are used for this purpose in a preferably non-aqueous solvent, the halohydrins X = Hal, Y = OH and Y = OH, Y = Hal being obtained. Protonic acids such as toluenesulfonic acid and trifluoroacetic acid lead to 12,13-diols in the presence of water, which are subsequently acylated (e.g. with carboxylic acid anhydrides and pyridine or triethylamine / DMAP) or alkylated (alkyl halides and silver oxide). The 3- and 7-hydroxy groups can be temporarily protected as formate (cleavage with NH 3 / MeOH) or p-methoxybenzyl ether (cleavage with DDQ).
Verbindungen gemäß der allgemeinen Formel 2 sind aus Epothilon A und B sowie deren 3-O- und/oder 7-O-geschützten Derivaten durch Reduktion, z.B. mit NaBH4 in Methanol erhältlich. Sind dabei 3-OH und/oder 7-OH reversibel geschützt, so können nach Acylierung oder Alkylierung und Entfernen der Schutzgruppen 5-O-monosubstituierte, 3,5- oder 5,7-O-disubstituierte Derivate der allgemeinen Formel 2 erhalten werden. Compounds according to general formula 2 can be obtained from epothilones A and B and their 3-O- and / or 7-O-protected derivatives by reduction, for example with NaBH 4 in methanol. If 3-OH and / or 7-OH are reversibly protected, 5-O-monosubstituted, 3,5- or 5,7-O-disubstituted derivatives of the general formula 2 can be obtained after acylation or alkylation and removal of the protective groups.
Verbindungen gemäß der allgemeinen Formel 4 werden aus Epothilon A und B oder ihren 3-O- und/oder 7-O-geschützten Derivaten durch Ozonolyse und reduktive Aufarbeitung, z.B. mit Dimethylsulfid, erhalten. Die C-16-Ketone können anschließend nach dem Fachmann geläufigen Standardverfahren in Oxime, Hydrazone oder Semicarbazone umgewandelt werden. Sie werden weiterhin durch Wittig-, Wittig-Horner-, Julia- oder Petersen-Olefinierung in C-16/C-17-Olefine überführt.Compounds according to general formula 4 are obtained from epothilones A and B or their 3-O- and / or 7-O-protected derivatives by ozonolysis and reductive work-up, for example with dimethyl sulfide. The C-16 ketones can then be converted into oximes, hydrazones or semicarbazones by standard methods known to those skilled in the art. They are further converted to C-16 / C-17 olefins by Wittig, Wittig-Horner, Julia or Petersen olefination.
Durch Reduktion der C-16-Ketogruppe, z.B. mit einem Aluminiumoder Borhydrid, sind die 16-Hydroxyderivate gemäß der allgemeinen Formel 5 erhältlich. Diese können, wenn 3-OH und 7-OH mit entsprechenden Schutzgruppen versehen sind, selektiv acyliert oder alkyliert werden. Die Freisetzung der 3-OH- und 7-OH-Gruppen erfolgt z.B. bei O-Formyl durch NH3/MeOH, bei O-p-Methoxybenzyl durch DDQ.By reducing the C-16 keto group, for example with an aluminum or borohydride, the 16-hydroxy derivatives according to general formula 5 can be obtained . If 3-OH and 7-OH are provided with appropriate protective groups, these can be selectively acylated or alkylated. The 3-OH and 7-OH groups are released, for example, in the case of O-formyl by NH 3 / MeOH, in the case of op-methoxybenzyl by DDQ.
Verbindungen der allgemeinen Formel 7 werden aus Epothilon A und B oder deren 3-OH- und 7-OH-geschützten Derivaten durch basische Hydrolyse erhalten, z.B. mit NaOH in MeOH oder MeOH/Wasser. Vorzugsweise werden Verbindungen der allgemeinen Formel 7 aus Epothilon A oder B oder deren 3-OH- oder 7-OH-geschützten Derivaten durch enzymatische Hydrolyse erhalten, insbesondere mit Esterasen oder Lipasen. Die Carboxylgruppe kann mit Diazoalkanen nach Schutz der 19-OH-Gruppe durch Alkylierung in Ester umgewandelt werden. Compounds of general formula 7 are obtained from epothilones A and B or their 3-OH- and 7-OH-protected derivatives by basic hydrolysis, for example with NaOH in MeOH or MeOH / water. Compounds of the general formula 7 are preferably obtained from epothilone A or B or their 3-OH- or 7-OH-protected derivatives by enzymatic hydrolysis, in particular with esterases or lipases. The carboxyl group can be converted into esters with diazoalkanes after protection of the 19-OH group by alkylation.
Ferner können Verbindungen der Formel 7 durch Lactonisierung nach den Methoden von Yamaguchi (Trichlorbenzoylchlorid/DMAP), Corey (Aldrithiol/Triphenylphosphin) oder Kellogg (omega-Bromsäure/Caesiumcarbonat) in Verbindung der Formel 1 umgewandelt werden. Einschlägige Arbeitsmethoden finden sich beiFurthermore, compounds of the formula 7 can be converted by lactonization using the methods of Yamaguchi (trichlorobenzoyl chloride / DMAP), Corey (aldrithiol / triphenylphosphine) or Kellogg (omega-bromic acid / cesium carbonate) in conjunction with the formula 1 .
